Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an apparatus for polishing the surface of root vegetables such as potatoes and small potatoes after washing with water.

(Prior art) Conventional polishing of root vegetables such as potatoes (hereinafter simply referred to as potatoes) after washing with water is often done manually using a cloth. The polishing device used is a conveyance path formed by arranging a plurality of sponge rolls with uniform wall thickness over the entire surface and integrally disposed around the surface, and a plate-shaped sponge fixed above the conveyance path. Polishing is done by rubbing between a sponge roll and a plate-shaped sponge while feeding the material.

(Problems to be Solved by the Invention) Manual polishing work has the drawbacks of being time-consuming and high-cost. In addition, in the conventional polishing mechanism using a sponge seal and a plate-like sponge, since the sponge roll is an integral piece, it cannot sufficiently deform along the shape of the potato, and the whole potato cannot be thoroughly polished. Furthermore, if the potato was strongly pressed with a sponge to solve this problem, the sponge roll would feed the potato too quickly, causing the potato to be discharged before sufficient polishing could be achieved.

An object of the present invention is to solve these conventional drawbacks and interlayer points and to provide an apparatus that can thoroughly and uniformly polish potatoes.

(Means for Solving the Problems) The gist of the present invention that solves the problems is as follows: 1) A plurality of rotating cylinders are arranged in series on the conveyance path for root vegetables such as potatoes, and the outer periphery of each rotating cylinder is aligned in the direction of the rotation axis. It is divided into a plurality of sections, and a plurality of thick sponge bodies are installed around the outer circumferential surface of each section so as to be separated by a required distance and fixed at one end. A polishing device for root vegetables, the outer periphery of which is covered with the same sponge body, and a presser sponge is provided above the rotary tube to which these sponge bodies are attached. Claim 1, wherein one end of the sponge body is fixed to a plurality of suspended shafts, and the sponge body is disposed around the rotating cylinder.
3) The apparatus for polishing root vegetables according to claim 1 or 2, wherein the presser sponge is provided in such a manner that the upper end of the presser sponge is fixed and the lower part is swingable from side to side. 4) A presser sponge is required. Claim 3 divided into multiple parts with a width of
5) A plurality of rotary tubes are arranged in series on the conveyance path for root vegetables such as potatoes, and
The outer periphery of each rotary tube is divided into two or more sections in the direction of the rotation axis, and each section is individually wrapped with a thick annular sponge body with multiple large recesses on the outer circumferential surface. 6) A polishing device for root vegetables comprising a presser sponge provided above a rotary tube equipped with a rotary tube. Polishing device 7) Claim 6 in which the presser sponge is divided into a plurality of pieces of required width.
In the described root vegetable polishing device.

(Function) In the present invention, the sponge body wrapped around each rotary tube forming the conveyance path is divided into a plurality of sections in the direction of the rotation axis and attached independently. Therefore, when a potato is pressed against the sponge body, the sponge body will respond to the unevenness of the potato depending on the section.
Compression deforms along the bend. This deformation is much easier to compress and deform than a one-piece long sponge because the width is short and it is not affected by tension from other parts of the sponge, and it takes the shape of a potato. along the entire surface of the potato. In particular, if the presser sponge is divided into a plurality of pieces along the longitudinal direction, the adhesion to the potato will be further improved. Therefore, as the rotary cylinder rotates, the sponge body comes into close contact with the potato and polishes the potato uniformly and over the entire surface. This can be done more effectively by dividing the divided sponge body into a plurality of parts and disposing them along the circumference of the rotary cylinder. If there is a large drop in the thickness of the sponge body at the seam of the sponge body, or if a large recess is formed in the annular sponge body, the potatoes will fall into the seam or four parts of the sponge body and stagnate for a short time, causing rotation nodes. Even though the rotation speed is the same, the feeding speed of the potato is slowed down to ensure a long polishing time. Moreover, this combined with the ability to move the potato's posture made it possible to polish the potato even more thoroughly and to the point of light.

Furthermore, if the upper end of the presser bluff is fixed and it can swing freely, the upper presser bluff will adapt to the potatoes and effectively polish the potatoes, slow down the feeding speed of the potatoes, and increase the rotation speed of the rotary joint. The polishing force can be increased by

(Example) Examples will be described below based on the drawings.

First Embodiment (See Figures 1 to 5) The embodiments shown in Figures 1 to 5 are embodiments of the invention according to claims 1 to 3, in which the sponge body extends in the axial direction and circumferential direction of the rotating cylinder.
